I don't think the response to the question about "reasonable faith" was adequate. A posteriori belief is not a matter of evidence alone, it's a matter of falsifiability. Years of falling apples don't prove Newton was right or that the force we call gravity will continue to operate in the future, but his observations have been tested and verified (unless and until faced with contrary evidence). It's reasonable to believe in gravity. By contrast, most claims of faith -- e.g., Intelligent Falling -- cannot be tested even in principle, let alone in practice. It's not that there isn't any evidence, but that adequate evidence is impossible.

There are other good videos there, but the Crockford lectures are better than good -- for programmers, they're the best introduction to the language available, bar none, and go further and at a higher level than most "advanced" resources. Even if you already know (or think you know) JavaScript, watch them!
